| Abstract: | Abstract Two new dimeric complexes of Ni and Co with pyridine 2,6-dicarboxylic acid were synthesized, the structure of both these complexes
were determined by single crystal X-ray crystallography and was characterized spectrally with the help of IR and UV spectrometers
and the magnetic moments of both the reported complexes were recorded. Both of these complexes crystallize in the monoclinic
space group P 21/c1. For the dimeric cobalt complex, formula C14 H21 Co2 N2 O15; a = 8.3950(3) ?; α = 90°, b = 27.3702(8) ?; β = 98.211(2)°, c = 9.6235(3) ?; γ = 90° and Z = 3. For the dimeric Nickel complex, formula C14 H21 Ni2 N2 O15, a = 8.330(10) A; α = 90°, b = 27.266(5) A; β = 98.61(10)o, c = 9.653(10) A; γ = 90° and Z = 4. Both the dimeric complexes were observed to be hexa-coordinated with two different types of donor atoms (nitrogen and
oxygen). Details of the synthesis, structures and spectroscopic properties have been discussed. |
